UNIVERSAL JOINT.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application led July l0, 1905. Serial No. 269,060.

To all whom, it nea/y concern.

Be it known that I, PATRICK L. HnssEY, a citizen of the United States ofAmerica, residing at Oleveland,in the county ofOuyahoga and State ofOhio, have invented certain new and useful Improvements in UniversalJoints; and l hereby declare the following to be a full,clear, andexact-description of the invention, such as will enable others skilledin the art to which itpertains to make and use the same.

This invention relates to improvements in universal joints.

The object of this invention is to provide a joint of this characterwhich will be very compact and which will present a smooth eXteriorsurface.

Another object of this invention is to simplify the constructionandassembling of joints of this character and to provide means fortaking up the wear on the bearing parts of the joint and also to providemeans for holding a quantity of a lubricant around the bearings of thejoint.

The invention consists in providing a bearing-carrying member for thejoint members arranged to incase the joint members and having such anarrangement of parts that the joint members may be inserted therein fromopposite sides, each joint member being seated in the bearing-carryingmember by first introducing one member of the fork thereof into thebearing-carrying member and allowing it to travel past its normalposition and then introducing the other member of the fork into thebearing-carrying member and then centralizing the joint member in thecasing.

My invention further consists in providing new und improved end piecesfor the casing which will eiectually prevent the escape of oil from thecasing, while allowing the joint members the greatest possible range ofmovement.

My invention further consists in providing adjustable bearings for thetrunnions on the joint members and new and improved means for lockingsaid bearings in their proper adjustment.

My invention further consists in the features of construction andcombination of parts, as described in the specification, pointed out inthe claims, and illustrated in the drawings.

In the accompanying drawings, Figure 1 is a side elevation of myuniversal joint. Fig. 2 is an end elevation of same. Fig. 3 is a sectionon line 3 3, Fig. 4. Fig. 4 is a view showing the bearing-carryingmember in central section and the joints in elevation with a part of oneof the joints broken away. Fig. 5

is a section on line 5 5,. Fig. 4.

Referring to the drawings, it will be seen that the joint members properare in every way identical, each joint member comprising a shank portion1, which is provided with a forked end portion 2, the fork members ofwhich are provided with trunnions 4. Each trunnion 4 is tapered towardits ends preferably in the form of altruncated cone, and in the endthereof is formed a pocket 10, which constitutes a grease-cup. Thebearing member comprises a shell 5,- preferably in the form of a broadring, in which are formed two pairs of openings 6. vThe openingsconstituting each pair are arranged diametrically opposite each other,and the pairs of openings are arranged, preferably, at a right angle toeach other. Around each of the openings 6 on the interior surface ofthe-shell 5 is formed an annular interiorly-screw-threaded flange 7.Strengthening-ribs 8 are arranged on the interior surface of the shell5, extending between the said annular flanges 7. Around each of theopenings 6 on the exterior surface of the shell 5 is formed a seat 9. Ineach of the openings 6 in the shell 5 is arranged an adjustable bearingwhich comprises an eXteriorly-screw-threaded bearing-ring 12, which ispreferably provided with a cap 13, which is arranged to iit into theseat 9 in the shell 5, and the outer surface of the said cap 13 isarranged to lie flush with the outer surface of the said shell 5, sothat the whole eX- terior surface of said bearing-carrying member isperfectly smooth. The openings 14 in the bearing-rings for receiving thetrunnions on the joint membersiare tapered to correspond to the taper onthe trunnions. Slots 15 are formed in the'caps 13 for receiving the end.of a tool by means of which the bearings can be screwed into theopenings 6. It will be readily seen that owing to the shape of thetrunnions and the corresponding shape of the openings in thebearing-rings perfect adjustment of the bearings can be secured at thctime the joint is assembled and also all the IOO wear can be readilytaken up and compensated from time to time by screwing in the saidbearings. In order to hold each bearing 1n IIO j and part of whichextends beyond the said seat 9, so that only a portion of the saidpocket is covered by the cap 13 on the bearing-ring.v

In the under surface of the cap 13 is formed a series of depressions 19,which are arranged to register with the pocket 18. In the pocket 18 islocated a dog 20, beneath which is arranged a coil-spring 21, thetendency of which is to force the dog above the top of the pocket,

and a portion of said dog will therefore enterl will be perfectlyoil-tight and dust-proof, end

pieces are provided for the shell 5, each of which comprises a piece ofleather or other flexible non porous material 23, having a greater areathan the openings at the ends of the shell 5. Each end piece is arrangedaround the shank portion of the joint member, so as to rest on ashoulder 25 on said shank portion, and is clamped thereon by means of ascrewthreaded ring 26, which engages a screwthread 27, formed on theshank portion. The outer edge of each of the end pieces 23 is clampedbetween two annular plates 28 and 29, which are secured together bymeans of rivets 30, and the said plates 28 and 29 are screw-threaded, soas to screw into the ends of the shell 5. The excess of material in theend pieces Q3 is disposed in crimps or folds 24. These end pieces offerabsolutely no resistance to the movement of the joints and together withthe shell 5 form an absolutely dust-proof and oil-tight easing.
